Advances in quantum technology might allow astronomers to circumvent age-old issues that limit the size of optical observatories ...

Everyday life on the internet is insecure. Hackers can break into bank accounts or steal digital identities. Driven by AI, attacks are becoming increasingly sophisticated. Quantum cryptography ...

Quantum physicists have uncovered a bizarre phenomenon in which photons appear to spend a “negative” amount of time ...

Entangled photons are at the heart of a variety of different and powerful quantum applications. By exploiting this unique quantum phenomenon, in which information correlates between two or more ...

In a laboratory at Oxford University, scientists have achieved something that once seemed science fiction: they made two separate quantum computers work together as one. Instead of being connected by ...

Scanning-based method offers greater single-photon detection efficiency and other advantages compared to camera-based methods ...

Every message we send online, whether a bank transfer or a meme, relies on light. Tiny pulses travel through fiber-optic cables, bouncing between nodes that amplify the signal every few dozen ...
